用于光谱探测的非马尔可夫量子轨道

Non-Markovian quantum trajectories for spectral detection

M. W. Jack, M. J. Collett, D. F. Walls

摘要:

我们从测量理论的角度给出了开放系统的非马尔可夫量子轨道的公式。在我们的治疗中,有三种不同的方式,其中非马尔可夫行为可能会出现;浴(水库)和系统之间的模式依赖耦合,分散浴,并通过光谱检测输出到浴。在前两种情况下,非马尔可夫行为是内在的相互作用,在第三种情况下,非马尔可夫行为来自检测方法。我们专注于详细的轨迹,模拟实时光谱检测从本地化系统发出的光。在这种情况下,非马尔可夫行为产生于后来检测到的粒子发射时间的不确定性。本文给出了用计算机模拟的方法对强驱动二能级原子的自发发射进行光谱探测的结果。

英文摘要:

We present a formulation of non-Markovian quantum trajectories for open systems from a measurement theory perspective. In our treatment there are three distinct ways in which non-Markovian behavior can arise; a mode dependent coupling between bath (reservoir) and system, a dispersive bath, and by spectral detection of the output into the bath. In the first two cases the non-Markovian behavior is intrinsic to the interaction, in the third case the non-Markovian behavior arises from the method of detection. We focus in detail on the trajectories which simulate real-time spectral detection of the light emitted from a localized system. In this case, the non-Markovian behavior arises from the uncertainty in the time of emission of particles that are later detected. The results of computer simulations of the spectral detection of the spontaneous emission from a strongly driven two-level atom are presented.
